Abstract

A system and method provides for tracking of an object. A personal digital key (PDK) includes a profile uniquely associated with the object. A reader is configured to wirelessly communicate with the PDK. The reader receives profile information from the PDK. A tracking server is configured to communicate with the reader. The tracking server is configured to track and log location information of the PDK associated with the object. The location information is received from the reader. A computing device is configured to communicate with the reader and the tracking server, the computing device configured to display data on a display device responsive to receiving the location information from the reader.

5. The system of claim 3, wherein in response to the alert server receiving information indicating that a monitored PDK is outside or has entered a predefined range or that the a monitored PDK is unexpectedly detected or not detected, the alert server is further configured to generate an alert.

6. The system of claim 4, wherein the PDK includes a temperature sensor, wherein the tracking server is configured to track and log temperature information of the PDK associated with the reader, wherein the data includes temperature data, and wherein in response to the alert server receiving information indicating that a monitored temperature is outside or has entered a predefined range, the alert server is further configured to generate an alert.

7. The system of claim 1, wherein the PDK includes an I/O line communicatively coupled to the object to monitor the object by receiving sensor or object data and wherein the tracking server is configured to track and log the sensor or object data received by the PDK associated with the reader.

8. The system of claim 7, further comprising:

an alert server, the alert server configured to receive data from an alert editor and automatically provide updates and alerts for monitored objects, wherein the data received from the alert editor includes alert identifiers and objects associated with the alert identifiers and wherein the data includes predetermined sensor or object data criteria that when met, or not met, the alert server is further configured to generate an alert.

9. The system of claim 8, wherein if the predetermined sensor or object data criteria are met, or not met, the alert server is further configured to output to and create a response at the monitored object using the PDK'"'"'s I/O.

10. The system of claim 9, wherein the response created at the monitored object helps identify the object creating the alert, the type of alert created or both.

11. The system of claim 1, wherein the location information is based on triangulation, the nearest reader or both.

12. The system of claim 1, wherein the data displayed on the display device includes a floorplan of a monitored area.

13. The system of claim 12, wherein the data displayed on the display device includes a location of the object on the displayed floorplan.

14. The system of claim 12, wherein the data displayed on the display device includes a location of a user or the computing device requesting to locate or track the object.

15. The system of claim 1, wherein the information logged by the tracking server is used to generate a report, and wherein the report includes historical information associated with locations with the object.

16. The system of claim 1, wherein the information logged by the tracking server is used to generate a graphical representation, wherein the graphical representation includes historical information associated with the object.

17. The system of claim 16, wherein the graphical representation includes real-time tracking of the object.

18. The system of claim 1, wherein the tracking server is further configured to receive an identified target object and track and log location information for the identified target object.

19. The system of claim 18, wherein the data displayed on the display device includes the location of the identified target object and one or more floorplans of one or more monitored areas and wherein the tracking server updates the data displayed to continuously display the location of the identified target object as the identified target object changes location or moves between floorplans.

20. The system of claim 18, wherein the data displayed on the display device includes the location of the identified target object, one or more floorplans of one or more monitored areas and one or more other objects within a predefined range of, or closest to, the identified target object.

21. A method for tracking an object, the method comprising:
